<u>Answer</u>:
"The arrangement of atoms or ions in a crystal " is described by the terms body-centered cubic and face-centered cubic.
<u>Explanation</u>:
Face centred cubic system explains the crystal structure where an atom is present at each cubic corner of the crystal and the centre of each cube face. Meaningfully, a closed packed plane where at each "face of the cube" atoms touch the alongside face diagonals.
Whereas in body centric cube system has the lattice point present at the 8 corners of cell and an additional one at the center of the cell. Thus, both explains how the atom or ions are placed or arranged in a crystal.
Answer:
Ar
Explanation:
does not react with anything it has a full electron shell so it does not combine and it is a noble gas
Answer:
electrons
Explanation:
By particles im assuming you mean subatomic. The particle with the most energy in this case would be electrons.
Answer:
Explanation:
Half time is period required to desintegrating the half of the initial number of atoms. Then, the total time is:
